摘要
光催化材料在处理污水和能源生产领域具有较好的应用前景。目前已开发多种光催化材料,提出众多性能提升策略。其中含S型异质结Bi基光催化材料(BSHM)因其可见光响应、高氧化还原性能被广泛研究。对BSHM合成和应用研究有助于提升污水处理性能和探索能源生产的光催化途径。通过对BSHM合成原理、合成方法及应用效果进行梳理,厘清各原材料应满足的能带条件及合成过程影响因素,研究发现应用中大多数BSHM相比原材料性能提升2倍以上,部分研究中对特定产物选择性达80%以上。在此基础上分析BSHM性能提升和产物选择性原因,为BSHM环境应用提供理论支持,为能源高选择性产出梳理研究方向。
Photocatalytic materials have good application prospects in wastewater treatment and energy production.At present,a variety of photocatalytic materials have been developed and numerous performance improvement strategies have been proposed.Among them,S-type heterojunction Bi-based photocatalytic materials(BSHM)have been widely studied due to their visible light response and high redox performance.The research on the synthesis and application of BSHM is helpful to improve the performance of wastewater treatment and explore the photocatalytic pathway of energy production.By sorting out the synthesis principles,synthesis methods and application effects of BSHM,the energy band conditions that each raw material should meet and the influencing factors of the synthesis process were clarified.it was found that the performance of most BSHM in applications was more than 2 times higher than that of raw materials,and the selectivity of specific products in some studies was more than 80%.On this basis,the reasons for the improvement of BSHM performance and product selectivity were analyzed,providing theoretical support for the environmental application of BSHM and sorting out the research directions for the highly selective output of energy.
